Seven questions to always ask the existing boiler’s operator round up this article, written to save you time and save your client grief (and possibly money) before, during, and after the project. Pumps, pipes, asbestos, and budget are just a few areas where opportunity (or problems) await.
This law school design story moves on from rationales for early decisions to the specific next-phase design challenges. Team effort combines with DOAS, radiant ceiling panels, DCV, and setpoint fine-tuning to maintain this case’s appeal.
Perhaps the U.S.’s largest to-date Dedicated Outdoor Air System (DOAS) coupled with radiant ceiling panel (RCP) cooling and heating mechanical system is currently under construction at the Washington College of Law at American University (Washington).
Two engineers mine their collective experience for tips on designing, modeling, and operating hydronic radiant heating and cooling systems. From conceptual basics to control nuances, on to goals like maximizing deadband operation or deploying a hybrid system, the article circulates plenty of practical information for an array of radiant opportunities.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
